Label the parts of the cell cycle diagram and briefly describe what is happening:
A
Interphase - cell is growing and preparing for division.
B
G1 - growth and normal cell function
C S - DNA replication
D
G2 - growth, preparation for division, duplicate organelles
E
Prophase - nuclear envelope dissolves, mitotic apparatus set up, DNA condenses.
F
Metaphase - chromosome line up in center
G
Anaphase - sister chromatids separate and are pulled to poles of cell.
H
Telophase - nuclei reform, DNA relaxes into chromatin, cleaveage furrow or cell plate forms
I
Mitosis - nuclear division
J
Cytokinesis - the rest of the cell divides
1) Chromosomes move to the middle of the cell during what phase?
2) What are sister chromatids?
